A man crushed to death by a vending machine wakes up reincarnated as one, dropped into a dungeon with no way to move and no words beyond a handful of canned phrases. Everything changes when the hunter Lammis finds him, names him Boxxo, and starts hauling him around on her back: his added weight helps her rein in the raw strength of her Blessing of Might. Boxxo repays her with drinks and gear pulled from his old-world memory, and their odd partnership starts drawing attention across the dungeon. This is the original web novel the manga adapts.
